Specification of Letters Patent. I Patented Dec, 2%, igflg,

Application filed March 14, 1907. Serial No. 362,310.

To all whom it may concern:

Be 'it known that I, EDWARD G. BUDD, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Improvement inCushions, of which the following is a specification. p p This inventionconcerns cushions for various uses and adapted particularly for use asseat-cushions for seats of the type commonly employed in railway cars.

The object of the invention is to efiect certain improvements in theconstruction of cushions for these uses, to the end that a cushion isprovided which possesses great strength, which can bemanufactured atsmall cost, which is provided with means for facilitating the attachmentof the covering material of the cushion to the frame, and which isconstructed largely or entirely of metal, so as'to be substantially orentirely fireproof.

In accordance with my invention, the cushion consists of a metallicframe, on which are mounted spiral springs for yieldingly supporting thecovering material. The longitudinal or side members of the metallicframe are made from sheet-metal strips pressed into form so as toprovide open space between the opposite sides thereof and thus securegreat strength. The end members of the frame are metallic castings, theends of which are specially formed, in order that they may be readilysecured to the ends of the sheet-metal side members. Both the castingsfor the end members and the sheetmetal side members have grooves formedtherein to receive strips to which the edges of the covering materialmay be tacked, these grooves being open only at the bottom of thecushion, so that the tacking strips are protected by the metal on allsides except that to which the covering is secured.

The preferred embodiment of my invention is illustrated in theaccompanying drawings, in which s Figure 1 is a bottom view of thecushion; Fig. 2 is a section on line 2-2 of Fig. 1; and Fig. 3 is asection on line 33 of Fig. 1.

Referring to these drawings, the frame of the cushion is of rectangularshape and consists of the side members 1 and 2 and the end Each of theside members 1 and 2 is formed of two sheet-metal strips 4. and 5,pressed to the cross-sectional shape shown in Fig. 2, so as to provideopen space between the opposite sides thereof, in order to securegreater strength. The strip 5 is bent longitudinally to form three sidesof the rectangle of the frame-piece, and at one'edge has an outwardlyextending flange 6. At its other edge, the strip 5 is bent outwardly asshown at 7 and then downwardly to provide a flange 8 parallel to theside members of the rectangle. The strip at has a fold 9 at one of itslateral edges, inclosing the flange 6 on the strip 5. At its otherlateral edge, it is provided with a downwardly extending fold l0inolosing the flange 8 at the other edge of the strip 5. The two stripsthusconstructed constitute a frame-member possessing great strength,

of the strip 5 provide a groove open at the bottom of the frame-member,in which is received a strip 12 of paper, wood or any other suitablematerial, to which the covering material of the cushion may be tacked.The strip 12 may be impregnated with fireproofing compound, if desired.

The end members 3 and 3 of the frame are castings, each having at itsend offsets 13 and 14: adapted to enter within the ends of the sidemembers 1 and 2. Rivets or bolts may then be inserted through openingsin the side members and these offsets to secure One end of each of theend members 3 and 3 may be rounded off, as shown in Fig. l, and each ofthese members has a groove formed therein, corresponding in size to thegrooves in the side members 1 and 2 and alining therewith. The cushionshown in the drawings is adapted particularly for use 'in seats of thetype employed in sleeping cars, and the end members 3 and 3 aretherefore formed to facilitate moving the cushion to a forward position,in which, with the back-cushion and the seatand back-cushions of anadjacent seat, it forms a bed. For this reason, the end members 3 and 3have grooves formed in the under side thereof, with inwardly extendingribs l5 at their lower edges, adapted to coact .:with the head of a studon the frame which :supports the cushion. Also, these end members havedepressions 16 formed therein to receive the heads of these studs whenthe cushion is in the rearward position.

the ends of the frame members together.'

and the flange 8 and fold l0 and the side 11 The flange 6 and fold 9 oneach of the side members 1 and 2 constitute a' flange extending inwardlof the frame, and a plurality of channele metallic slats 17 extend,across the frame and are secured at their ends by rivets 18 to theseflanges. These slats 17 support a plurality of spiral springs 19, andflat springs 20 extend across and are supported by the upper ends ofthese spiral s rings 19. The covering material 21 and, if desired, asheet of felt or other upholstery material' 22, are drawn over the flatsprings 20, the edges of the covering 21 being carried down over thesides of the cushion and under the edge of the frame, Where they aresecuredto the strips 12 by tacks 23.

The cushion thus constructed is of great strength, both because of theconstruction of the members of the frame and because of the The tackingstrips 12'afio'rd means for readily securing the covering material tothe frame, and these strips are amply protected by the metallic partsinclosing them. The cushion thus constructed can be manufactured atcomparatively small cost. If desired, the covering materialof thecushion may be formed of woven metallic strands, the upholstery material22 omitted or replaced by a woven fabric of flat spring strips and thestrips 12 impregnated with a inclosing said flanges, said strips beingbent I fireproofing compound, so that the structure is entirelyfireproof. I

Having now described my invention, what I claim as new therein anddesire to secure by Letters Patent is as follows:-

1. In a cushion, a frame consisting of frame members secured together attheir ends, certain of said members being of sheetsite sides of themember and to provide an integral portion extending outwardly from theupper edge of the member and then downwardly to form a lengthwise grooveopen at the bottom of the member, substantially as setforth.

2. In a cushion, a frame consisting of frame members secured together attheir ends, certain of said members consisting of two sheet-metal stripsone having flanges at its lateral edges and the other having foldslongitudinally intermediate their edges to provide open space betweenthem, an integral flange extending inwardly of the frame, and anintegral flange extending outwardly from the upper edge of the memberand then downwardly to form a lengthwise groove open at the bottom ofthe frame, sub

'stantially as set forth.

' frame, substantially as set forth.

4. In a cushion, the combination of a frame consisting of side and endmembers secured together at their ends, said side members being ofsheet-metal and said end members being metallic castings each having alengthwise groove and a depression in the under side thereof and ribsextending inwardly at the bottom of said groove,

springs supported on said frame, and a covering extendlng over saldsprings and secured at its edges to'said frame, substantially as setfort 5' In a cushion, a rectangular frame consisting of side and endmembers, said side members being formed of sheet-metal strips pressed toprovide open space between opposite sides thereof and said end membersbeing castings each havin integral offsets on one side thereof, one ajacent to each end, entering within and securedto the ends of saidsheet-metal members, each of said meme bers having a lengthwise groovetherein forsprings and secured at its edges to said strips,substantially as set forth.
